Create a Persona

Creates a Persona on a Brand. A Persona describes one audience that the brand speaks to. The body and both ends of the age range are optional, because you write a Persona one part at a time. The slug is unique in the Brand, not in your organization. The answer is 409 if the slug already exists on this Brand.

POST/context/brands/{slug}/personas

Authorization

Responses

201

The Persona as created, at revision 1. An unwritten body comes back null, which is a normal state rather than an error.

ageMaxnumber | nullrequired

ageMinnumber | nullrequired

Each bound is independently optional, so "35+" is expressible.

bodystring | nullrequired

Who this audience is, in markdown, or null when nobody wrote it. A listing answers hasBody, never the body.

brandIdstringrequired

createdAtnumberrequired

Milliseconds since the Unix epoch, UTC.

createdBystringrequired

descriptionstringrequired

idstringrequired

namestringrequired

revisionnumberrequired

Increments on every write. Send it back as base_revision to edit; a stale one answers 409.

slugstringrequired

updatedAtnumber | nullrequired

Milliseconds since the Unix epoch, UTC.

400

The request does not match the schema of this operation: a field is missing or has the wrong type, or the body is not valid JSON. error is invalid_request, and issues names each field. Nothing was changed.

issuesobject[]required

One entry for each field that does not match.
